Abstract: The ship-borne electro-optical tracking and fire control system is a kind of long-range monitoring, tracking and fire attack device, which can be divided into discrete system and integrated system according to the architecture. The structural forms, sensor configuration, range and relationship with fire control system of typical electro-optical directors such as MSP500 in Germany, Medusa MK4 in Italy, 2500 in England, Toplite in Israel, SeaFLIR 280-HD and 380-HD in America, EOS500 in Sweden, EMOS NG and PASEO in France were compared and analyzed. The structure of electro-optical directors was gradually developed from T-type to U-type, the band of electro-optical sensor was developed from single band to multiple band, and the function of electro-optical tracking system was changed from single function to comprehensive multi-function. With the intensification of modern naval warfare, the ship-borne electro-optical tracking and fire control system will develop towards multi-sensor cooperation detection, information fusion, multi-target identification, intelligent tracking and mission diversification.
